Canon EF 24-105mm F/4L IS USM VS Canon 28-135mm IS USM

Mark D. Segal compared both Canon EOS 24-105mm F/4 L IS USM with Canon EF 28-135mm IS USM and wrote:

“My findings and comparison of key specifications: Insignificant vignetting with either lens; The L lens has generally superior contrast; The L lens displays generally less chromatic aberration, but some exists in the same places where the 28~135 had more; At 105mm it is hard to see much difference in resolution even at 100% magnification; At 28mm and 50mm the differences of sharpness/resolution are obvious even at f8, which should be in the range of the “sweet spot” for both lenses; 24mm really expands the image area considerably compared with 28mm; at the telephoto end 105mm is enough for me, considering that I also have a 70~300mm; Maximum telephoto aperture of f/4 versus f/5.6 (twice the amount of light).”

Photography Tip: Framing in Portraiture

Portrait Tutorial

Haje Jan Kamps, a DeviantArt member, wrote a good tutorial on “framing in portraiture”

“I spend a lot of time commenting on stuff on DA. One of my pet peeves is bad framing in portraiture. Not bad because it is different from the way I would have done it, but bad because some people don’t even think about framing or cropping. Lighting, the model, and other technical stuff is easy enough: Any monkey and his dog manages to set up a scene and point a camera at it. The trick is to somehow lure some context out of a photograph. This can be done in many different ways, but framing and/or cropping is the easist way to do it, in my opinion.”
